Title:
DIFFERENTIAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/104763
Kind Code:
A1
Abstract:
A differential device in which a transmission case is provided with: a first transmission member for which a first axis line is the center axis line; an eccentric rotation member coupled with a main shaft part rotatable around the first axis line and an eccentric shaft part for which a second axis line is the center axis line; a second transmission member that is arranged so as to face the first transmission member, and is rotatably supported by the eccentric shaft part; a third transmission member that is arranged so as to face the second transmission member, and is capable of rotating around the first axis line; a first speed varying mechanism between the first and second transmission members; and a second speed varying mechanism between the second and third transmission members. In said differential device, the second transmission member (8) is provided with a first half body (8a) supported by the eccentric shaft part (6e); a second half body (8b) facing the first half body, so as to sandwich the space (SP) therebetween; and a coupling member (8c) spanning the two half bodies. The first speed varying mechanism (T1) is provided between the first half body and the first transmission member (5), and the second speed varying mechanism (T2) is provided between the second half body and the third transmission member (9). A first spline boss (SB1) is disposed such that an interior edge (6ja) projects into the space. The differential device according to the present invention increases productivity, while allowing for a smaller device.
